Title: Anti-skid anti-spin regulation for vehicle wheels
Inventor: BERTLING HANNES
IPC: B60T8/34
Filed: 1983-04-28
Abstract: The sensor-controlled anti-skid control valves 6,7 in a hydraulic brake system are also used in conjunction with sensor-controlled solenoid valve 14 connected in feed line 3 from master cylinder 2 and with accumulator 13 to provide anti-spin regulation. During the anti-skid control mode and when valves 6,7 are in the return position fluid from the brakes is passed to and stored in accumulator 11. During the anti-spin control mode, when valves 6,7 are as shown, valve 14 is switched over so that fluid from accumulator 13 actuates the brakes. To ensure that anti-spin regulation can take place, suction pump 12 which can operate at low inlet pressures, may under electronic control, intermittently draw fluid from accumulator 11 to change accumulator 13 or the connected brake circuit. At a predetermined minimum pressure at the inlet of accumulator 11, valve 16 opens to allow replenishment thereof from master cylinder 2. <IMAGE>

Title: Treatment of meat
Inventor: MORAN ARTHUR WILLIAM
IPC: A22C7/00
Filed: 1983-08-05
Abstract: Boned-out pieces of meat, e.g. ham or bacon are treated to yield sliced products. In the case of bacon, the bacon pieces are first compressed in a press (5) to attain a desired transverse cross-section. Then the compressed bacon pieces are passed through an elongate duct (1) which extends through nitrogen tunnel (3) so that the bacon pieces are chilled or frozen to a limited extent before passing to the slicer (6). Thus handling is reduced and also by chilling and squaring off the ends of the bacon pieces, and freezing adjacent bacon pieces together, wastage during slicing is obviated. In the case of ham, the ham is introduced into the press and passed through the elongate duct, which is heated, e.g. by steam or radiant heat, to cook the ham. <IMAGE>

Title: Introducing sample vessel into measuring chamber using sealable plunger
Inventor: LOHR WILLY
IPC: G01N21/76
Filed: 1983-10-26
Abstract: A measuring station 2 for a photometer has an aperture which connects a hollow measuring chamber 13 and the environment and through which a sample vessel 8 can be introduced into the measuring chamber 13 and/or removed from the measuring chamber 13. The sample vessel 8 is raised and lowered by a plunger 22 which is adapted to seal against the aperture by means of a sealing element 38, e.g. an O-ring. The sealing element 38 has a first position in which its periphery circumscribes a smaller area than the internal clear cross-section of the aperture, to permit the sample vessel 8 to be lifted into the chamber 13. The sealing element 38 can then be expanded radially into sealing engagement with the aperture to seal the plunger 22 to the walls of the aperture to prevent ingress of light. <IMAGE>

Patent GB-2153133-A (GB)
Title: Electric cables
Inventor: DIAMOND HUGH JAMES
IPC: H01B7/42
Filed: 1985-01-21
Abstract: Risk that a flash arising from an explosion or fire will travel along the interstices of a multi-core electric cable is substantially eliminated by laying up in the interstices preformed flexible elongate non- inflammable metallic fillers. At any transverse cross-section of the cable, each metal filler is of such foraminous form and of such thermal conductivity and heat capacity as to cool any hot gases, arising from an explosion or fire, flowing along the cable interstices to an extent sufficient to prevent longitudinal passage of a flame or flash along the interior of the cable. The metal fillers operate in a similar manner to the wire-gauze of flame safety lamps used in mines. The metal filler may be a gauze of steel or copper or of non-magnetic material of high electrical resistance to reduce induction effects. <IMAGE>

Title: Brake pressure control unit for a motor vehicle hydraulic brake system
Inventor: SCHOPPER BERND
IPC: B60T11/34
Filed: 1985-03-26
Abstract: A brake pressure control unit, for a dual circuit brake system, comprises two series arranged pressure control valves respectively controlling a pressure medium connection between the pressure medium source and the rear wheel brake cylinder of each circuit. One of said pressure control valves is formed as a proportioning valve provided with a stepped piston (3), urged rightwards in the valve opening direction by a spring (43) while the second pressure control valve is a shut off valve (21) controlled by a balance piston (18). A further spring (47) is normally held compressed by fluid pressure acting in chamber (6) on transmission member (40), but on failure of pressure in the first circuit the spring expands so that step (49) of the member (40) abuts the piston step (48) thereby increasing the change-over pressure in the still intact brake circuit (II) since, in case of a displacement in the closing direction, both the control force and the force of the spring means (47) will have to be overcome by balance piston (18). <IMAGE>
Patent GB-2161241-A (GB)
Title: A hydraulically damped resilient mounting
Inventor: HEITZIG JURGEN
IPC: F16F13/26
Filed: 1985-05-21
Abstract: In a hydraulically damped resilient mounting of the type where an elastomeric spring 2 and a diaphragm 4 define two liquid-filled chamber 8, 9 which communicate via a throttle 17, a chamber 10 on the other side of the diaphragm (which would normally be at atmospheric pressure) can be subjected to a reduced pressure when desired. This causes the diaphragm 4 to deflect to the dotted line position which induces cavitation in the liquid. This renders the throttle 17 and therefore the hydraulic damper ineffective, thus removing a source of undesirable noise. When the mounting is used to mount a vehicle engine, vacuum is supplied from the manifold either selectively or automatically in response to sensed parameters. <IMAGE>

Patent GB-2240229-A (GB)
Title: Signal processor
Inventor: HEARD JAMES L
IPC: H04N5/365
Filed: 1985-10-09
Abstract: A signal processor for use with an imaging sensor system that provides enhanced video imagery, may be coupled to a FLIR system, for example, which comprises a plurality of detectors that are scanned across an image scene and reference temperature source during separate portions of each scan cycle. The signal processor comprises an input processor 21 coupled to the imaging sensor system which processes analog signals derived from each of the plurality of detectors. The input processor normalizes the analog signals relative to one another during the active portion of the scan cycle based upon stored data derived from a predetermined sensor responsivity calibration procedure. This normalization function equalizes the gains associated with all channels of the sensor system. The input processor also restores the DC levels of each of the sensor channels to respective DC values related to the reference temperature source during the inactive portion of the scan cycle. This function is performed during the calibration procedure and while the system is in operation. The input processor digitizes the signals which are applied to a scan converter 22, which stores the digitized signals and converts the stored signals into signals which are compatible with a video monitor employed to view the image. An output processor 23 is coupled to the scan converter 22 to process signals in a manner which permits software-controlled digitized image enhancement thereof, and which converts the enhanced signals into analog video output signals compatible with the video monitor. <IMAGE>

Title: Distributor rotor for ignition distributors of internal combustion engines
Inventor: HAUG HEINZ
IPC: F16F1/12
Filed: 1986-02-20
Abstract: The distributor rotor (10) has an insulator (11), which is secured on to the distributor shaft (12) and conducts the ignition energy delivered by the centre electrode (15) via the contact piece (14) to the distributor electrodes (13). A centrifugal electrode (23) is connected to the contact piece (14) by a spiral tension spring (21) and, whenever a critical speed of the distributor rotor (10) is reached, discharges the ignition energy to the side electrode (25) against the force of the spiral tension spring (21). The one eye (20) of the spiral tension spring (21) is suspended in an opening (29) of the centrifugal electrode (23) and the other eye (22) is suspended on a finger (19) of the contact piece (14). Both suspensions are made rigidly, i.e. free from reciprocal relative movements of the parts in contact with each other eg. by wedging (figure 4), distortion of the suspension against the eye, moulding around the eye or by the clamping action of plural turns of the eye against the suspension. <IMAGE>
